  • Materials having z-direction fibers and folds and method for producing same
    Patent number: 6867156
    Abstract: A method for producing a material having z-direction waves in which a layer of continuous fibers is conveyed on a first moving surface into a nip formed by the first moving surface and a second moving surface which is traveling at a slower speed than the first moving surface, resulting in formation of a plurality of z-direction loops in the fibers giving loft to the material and a wave pattern producing ridges on both major surfaces of the resultant nonwoven web. The method permits easy real time alignment of manufacturing parameters to produce a variety of materials. The method further produces lofty nonwovens at a commercially viable rate.
    Type: Grant
    Filed: March 30, 2000
    Date of Patent: March 15, 2005
    Assignee: Kimberly-Clark Worldwide, Inc.
    Inventors: Edward Jason White, Kurtis Lee Brown, John Herbert Conrad, Robert James Gerndt, Jose Enrique Maldonado
  • Dual capillary spinneret for production of homofilament crimp fibers
    Patent number: 6830640
    Abstract: Robust homofilament fibers are meltspun from a differently shaped dual capillary spinneret design to induce differential fiber morphology to produce crimping. Crimping may further be aided by quenching and drawing of the fibers.
    Type: Grant
